GAS-VALVE.

Specification of Letters Patent Patented we 16, 1908.

Application filed July 18, 1901. Serial No. 384,340. i

To all whom it ma concern:

Beitknownthat ,ABRAHMJARMOLOWSKY, a subject of the Czar of Russia, and aresident of the city of New York, borou h of Brooklyn, in-the county ofKings and tate of New York, have invented a new and Improved Gas-Valve,ofwhich the following is a full, clear, and exact description.

This invention relates to gas valves adapted to be used with fixtureshaving a plurality of-branches, each provided with anindividual burner,and has for its object to provide means for turning on or off apredetermined number of burners by a single operation.

Other objects relating to the specific con struction and specialarrangement of the several parts of my invention will be understood fromthe following description and accompanying drawings, in' which drawingslike characters of reference indicate like parts throughout the'views,and in which Figure 1 is a perspective view of a device embodying myinvention having four branch burners connected therewith; Fig. 2 is aver tical section of the corresponding device shown in Fig. 1; Fig. 3 isa sectional elevation taken on the line, 33 of Fig. 2; and Fig. 4 is ahorizontal section taken on the line 44 of Fig. 2.

As illustrated in the drawings, 1 represents a casing-which may be of.any suitable construction and provided with suitable apertures for amain supply pipe 2 and branch 3, 4, 5 and 6. The casing is also pro- W Ied with a conical bore 7 communicating" 'W1th said apertures for themain supplypipe and branch pipes, and adapted to recelve a correspondingconical plug 8 having a stem 9 WhlCll engages a sleeve 10 provided witha' finger piece 11, and detachably connected with the stem 9 by means ofa screw stud 12. The outer end of the stem 9 may be provided with anornamental device 13 of any desired construction. A cap 14 is secured tothe casing 1 by means of stud screws 15 or other wise, and a spring 16is arranged between the plug 8 and the inner surface of said cap so asto hold the plug 8 snugly in positionin the recess 7 of the casing. Theplug 8 has a hollow interior and the wall of the plug is provided withseparateseries of apertures 17, 18, 19 and 20 respectively, theapertures of one series being spaced from those of each of the otherseries.

A pointer 21 is connected with the sleeve pipe 5, and another of theapertures 18, 19

and ZO brought in alinement with the a erture of its respective branchpi en e. the stem 9 is turned farther to the left the ap ertures 17and-18 are out of alinement with the aperture of their respective branchpipes, leaving only the apertures 19 and 20 m almement with the branchipes 3 and 4, and if the stem9 is turned fart or to the left theap-"ertures 17, 18 and 19 will be out of ahnement with their respectivebranch pipes, leaving only one of the a ertures 20 in ahnement with thebranch p1 es 4. A still farther turn of the stem bring all of theapertures 17 18, 19 and 20 out of alinement with the aperturesof thebranch pi es and,

shut off the supply of gas from of the burners connected therewith.' Thestem 9 is held by means of the stop 23 against rotary motion to theright beyond where all of the burners engage one of the apertures of thedifierent series of the block. As one, two, three or four of the burnersare-opened by means of the rotation of the stem 9 and plu 8 connectedtherewith, the number so opene will be designated by the pointer 21 andthe figure or marking of the casing to which it I points, as illustratedin 3.

When it is desired to turn on any particular number of burners, thepointer 21 is made toregister with the desired number on the casing, andthe rotation of the plug 8 in turning the pointer to the desirednuifiber bring the the apertures of the proper number of series inalinement with the apertures of the branch p n the construction hereinshown and described, the several series of apertures in the plug 8 arearranged in the same horizontal plane. Such arrangement is not essentialto my invention, however, and if desired the apertures of each seriesmay be arranged in a dlfierent plane from the apertures of each of theother series.

7 Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

In a device of the character described, the

5 combination with a casing having a main aperture, a series of branchapertures, and a conical central bore, communicating with said main andbranch apertures, of a tubular plu engagin the conical bore of saidcasing 10 am? provide with a multi le series of apertures adapted toregister wlth the branch apertures of said casing, the apertures of eachseries of said plug increasing progressively i1} number, an a stemconnected withsaid u p Iii testimony whereof I have signed my 15 name tothis specification in the presence of two subscribing Witnesses.
